All envelopes are now in the mail except the Canadian ones, which will go tomorrow, and the ones with postage problems, which are plentiful this time. For future reference, use stamps only, not metered postage when providing a return envelope. My post office has refused to accept most classes of metered mail. I've notified all participants whose envelopes have postage issues.
Several people submitted extra blocks, and when I got down to the end, I had four extras, so I randomly included those in envelopes. If you have received 13 instead of 12, that is the reason.
I hope that all of you will enjoy your assortments of black, white & bright blocks. Thank you for permitting me to serve as your hostess.
